17 The 

Basics

We use a few simple terms in this manual to explain 
the features of the scanner. Familiarize yourself with 
these terms and the scanner's features, and you can 
put the scanner to work for you right away. Simply 
determine the type of communications you want to 
receive, and then set the scanner to scan those 
communications.

A frequency, expressed in kHz or MHz, is the tuning 
location of a station. To find active frequencies, you 
use the search function or refer to a frequency refer-
ence.

Besides searching within a selected frequency 
range, you can also search your scanner's service 
banks. Service banks are preset groups of frequen-
cies categorized by the type of services that use 
those frequencies. For example, many amateur 
radio frequencies are located in the HAM service 
bank.

When you search and find a desired frequency, you 
can store it into a programmable memory location 
called a channel. Channels are grouped into 
channel-storage banks. The scanner has 10 channel-
storage banks and each bank has 20 channels. You 
can scan the channel-storage banks to see if there is 
activity on the frequencies stored there.
